Hi,

had exactly the same problem. You need to update the dll for integrated authentication,  
must be `mssql-jdbc_auth-9.2.0.x64.dll` now as Sonarqube ships with  
`%SONARQUBE_HOME%\lib\jdbc\mssql\mssql-jdbc-9.2.0.jre11.jar`  
Get it here [Release notes for the JDBC Driver - SQL Server | Microsoft Docs](https://docs.microsoft.com/en-us/sql/connect/jdbc/release-notes-for-the-jdbc-driver?view=sql-server-ver15)  
Just put it on path - i simply used the /bin folder of the jdk - and it should work.
